Stnder (Versucli eines Syst. der Alcyonaria. Arch. Naturgcsch. 53. Jahrg. i. 1887, p. 22, and 

 Challenger Report vol.31, p. XXVII) ha.s followed Kor en & Daniels.sen ■), and like these anthors 

 added a fifth to the fonr groups of Kolliker: Gdndale(e with fam. GundulidcE^ genus GondtdlLor.'Daw. 

 but has otherwise restricted himself to the inserting of the later established genera into the families 

 of Kolliker (Sciophyllutn Verr. in fam. Pennahclida^ Svava Kor. Dan. in Stylatididce^ Gunneria Kor. Dan. 

 and Distichoptilum Verr. in ProtoptUida-). Later (Note prelim, etc. Camp, de rHirondelle 1890) he 

 has inserted into the fam. Ptcroridido' the new genus Gyrophylhtm Stud. Kiikenthal (Diagnosen 

 neuer Alcyonarien aus der Ausb. d. Deutschen Tiefseeexpedition. Zool. Anz. 25. Bd., 1902, p. 302) has 

 added still another (the sixth) group: Verticilladece: fam. Clmnndlida:, genera CImnella Kiikenth. 

 and Amphianthus Kkth. Bourne (Anthozoa in the treatise on Zoology edited by Ray Lankester, 

 part II, 1900) almost without any alteration — at all events, without any essential alteration — has 

 followed Kolliker; it has to be remarked, however, that he regards the two families of KoUiker Vir- 

 gidaridcB and Stylahdidcc. as subfamilies of one family Virgtdaridce ; Pcniiatulidm and PterocididcB Koll. 

 are regarded also as subfamilies; and the family Gondidids is placed beside, and in the same group 

 with these families; finally also FiDnculinidce and BathyptUidm are degraded to subfamilies of one 

 family, as are also the two families of Veretillinse. The system has been more highly modified in 

 Delage & Herouard (Traite de Zoologie concrete T. 2, Partie 2, 1902); here there are five groups: 

 I) Frondina [RenUla\ 2) UmbeUina ( UinbcU/da), 3) Juncina [Spicaim + Veretdlece. of Kolliker), 4) Pcnnina 

 [^ PennahdecB of Kolliker), ^Acaulinm {Gondid). The extent of the famihes remains otherwise almost 

 unaltered; the family Protocaulidcc of Kolliker, however, has been placed under the family Kopho- 

 belemnonhicE D. & H., and the genus Deidocaulon Marsh. & Fowler has been included in the same 

 family; the genus Cladiscus Kor. Dan. has been removed to the family Proioptilin(B\ the genus Svava 

 Kor. Dan. to the family Virg2darmce\ several genera of the same family, as Lygus Herkl, Radicipes 

 vS teams, as also some of the genera established by Gray in the ia.\\\\\\ Petmatulino' are also enumerated.
